Sentences with phrase «if black holes»

Most people are ignorant of astronomy or advanced physics, but if you asked them if black holes exist, you'd get a higher proportion agreeing than do with man - made global warming.

If the black holes are of unequal mass, then some of the energy may radiate more strongly in one direction, producing the equivalent of a rocket thrust.

Ripples in spacetime stirred up by merging black holes (SN Online: 6/1/17) should be slightly amplified if those black holes are spinning.

As we noted, the LHC will not destroy the world and as George Musser wrote to me after we recorded the interview, «I said something to the effect that scientists had stocked [stoked] concerns about black holes by saying the LHC would create particles not seen since the big bang, but those particles have been seen since the big bang, namely in natural processes such as cosmic ray collisions; therefore if black holes posed a threat, the universe would already be a goner.»

Elbert said he expects many more gravitation wave detections so that he and other astronomers can determine if black holes collide mostly in giant galaxies.

The paradox has it that if black holes are as we think, they must be surrounded by rings of fire, though that would violate general relativity.

If black holes are detected at the LHC, what would it mean for physics?

So the very fact that we exist here on earth to talk about these things tells us that even if black holes are produced, pretty much everything is very safe.

Kashlinsky shows that if black holes play the part of dark matter, this process occurs more rapidly and easily produces the lumpiness of the CIB detected in Spitzer data even if only a small fraction of minihaloes manage to produce stars.

If the black holes started out as paired stars, then they should spin in the same direction as their orbital axis.

«If the black holes were not spinning in the same direction as the orbit, that would probably be a pretty good indicator of the dynamical formation channel,» Rodriguez says.

If the black holes formed before they paired, then they could spin in any direction.

Even if black holes aren't responsible for forming galaxies, they are still extremely important to our understanding of the universe as a whole.

The paradox could also be resolved if black holes do not include a true singularity, or if, as Stephen Hawking has suggested, the Hawking radiation contains the information, albeit in a mangled and unreadable state.

If the black holes smash together and merge, the resulting hole recoils in the opposite direction.

Likewise, if black holes act like information mirrors, as Hayden and Preskill suggested, a particle falling into a black hole would be followed by an antiparticle coming out — a partner with the opposite electric charge — which would carry the information contained in the spin of the original particle.

But if the black holes instead find one another in the chaos of a star cluster, they could spin any which way.

Alfred Goldhaber of Stony Brook University in New York says that if black holes have charged plasma swirling around them, a photon's slowed movement through the plasma could make it behave as if it has mass, ruining the calculations.

If black holes don't exist, I ask Mersini - Houghton, what are those things at the hearts of most galaxies?

Here is where the deniers come in: If black holes keep sprouting paradoxes, the thinking goes, maybe the problem lies with our understanding of the black hole itself.

If black holes do exist, which they are pretty sure they do, then their gravitational signature dictates these «rules».

If black hole after all the scenario of quantum mechanical process have completed their interactions behave accordingly to Relativity equation to became eventually a tiny speck in space of high intensity mass with very strong gravitation wave could the telescope have picked up such polarization of light from some gravitated wave of dying star or black hole.

If the black hole «tunneled somewhere else and caused an expansion of new space and time, all of that matter would exit the other side all at once.

If black hole seeds come from stars, the process should have given every dwarf galaxy its own supermassive black hole.

If the black hole existed forever, the information might be «locked away» inside it.

If a black hole preserves information, he argues, then an unavoidable conclusion of Einstein's theory of gravity — that there's no way to tell if you're falling into a huge black hole — must be wrong.

Dopita describes the process as a kind of cosmic indigestion: «It is as if the black hole sucks in too much, too quickly, and it burps out gas.»

Likewise, if a black hole grows large enough to intersect a parallel three - dimensional universe in the extra dimensions, its decay properties would suddenly change.

The techniques are, in a sense, complementary to the «global» methods which Penrose pioneered: they can not handle «generic» collapse, where there is no special degree of symmetry, but they do produce a more quantitative picture of what would happen if a black hole were perturbed (for instance, by, a smaller object falling into it or orbiting close to it).

If the black hole eats a star every 30,000 years, that hot plasma could provide enough energy to power the gamma - ray bubbles.

But if a black hole is floating alone in space, no emissions would be observable coming from it.

For example if a black hole has a companion star, gas streaming into the black hole piles up around it and forms a disk.

While that is what would happen if a black hole bomb went off nearby, black hole bombs are not real.

And if a black hole rotates, as would be the case for a hole that forms from the collapse of a spinning star, it drags spacetime along with it, a phenomenon known as frame dragging.

Even if the black hole and neutron star remain in orbit, they will probably stay far apart.

If the black hole is spinning, it drags on the field, winding it into a tight cone at the rotational poles of the black hole.

Interestingly, the stars around the center of NGC 1600 are moving as if the black hole were a binary.

«It would be really wonderful if the black hole were cataclysmic now,» he sighs.

For example, if a black hole is modelled according to string theory — in which the universe is made of tiny, vibrating strings rather than point - like particles — there are pretty convincing arguments that say information can get out, according to Joseph Polchinski from the University of California in Santa Barbara, US.

These objects also get flung about by the gravity of the central IMBH, causing them to be found at greater distances from the cluster's center than would be expected if no black hole existed.

This method only works if the black hole is actively feeding on nearby gas.

«That is upsetting, the idea that you could set out with an electrically charged star that undergoes collapse to a black hole, and then Alice travels inside this black hole and if the black hole parameters are sufficiently extremal, it could be that she can just cross the Cauchy horizon, survives that and reaches a region of the universe where knowing the complete initial state of the star, she will not be able to say what is going to happen,» Hintz said.

«Simply put, if the black hole is small, the orbital periods at the innermost circular orbit are shorter, but if the black hole is big, the orbital periods are longer (smaller frequencies).»

«If a black hole is spinning, it drags space and time with it, and that drags the accretion disk, containing the black hole's food, closer towards it,» study lead author Chris Done, of the University of Durham in the United Kingdom, said in a statement.

«This can happen if the black hole isn't spinning that fast.»
